Hi Alan,

Thank you for sharing this to the Microsoft Community. We suggest you to run Hardware troubleshooter. Windows comes with this built-in troubleshooter. If you recently installed a new driver or plugged-in a hardware and face some things that are not
working as you’d like them to, use this troubleshooter. Please follow the steps below:

• On Cortana or search, type in Control Panel
• Type Troubleshooting in the search box on the upper right corner and hit enter.
• Click on Troubleshooting tab.
• Click on View all option on the upper left corner.
• Select the Hardware and Devices options from the list.
• Click Next to run the Hardware and Device Troubleshooter.

Once you're done, update us with the result.

 

The MiniTool register from disk worked for me

This worked for me. The MiniTool instructions. Background: at first when I went into powershell (admin not needed to list them) and type: Code:

In the resulting list of 29 items, Microsoft.Windows.SecHealthUI was NOT listed. It was totally missing. So none of the more common "re-register" steps would work because they require Get-AppxPackage to see it and on my system it couldn't. But the MiniTool approach gets at it from the file location on disk: C:\Windows\SystemApps\Microsoft.Windows.SecHealthUI_cw5n1h2txyewy This WAS there on my system. So, opening powershell admin (right click start menu) and running MiniTool's suggestion, namely, Code:

fixed it. It essentially reinstalled it. Then it appeared in the list returned from Get-AppxPackage and the "Open Windows Security" button in settings worked.
